As we will see in the following section, this singularity is cancelled in the full subprocess amplitude by a
corresponding singularity in the 3-body contribution. Subtracting the singularity (REF )
the remaining contribution to \( {\cal H}^{P, \phi _{\pi 2}^{EOM}}_{0-\lambda ,0\lambda }\)  vanishes in the photoproduction
limit, see Tab. REF . Hence, the only 2-body twist-3 contribution that survives
in the photoproduction limit is \({\cal H}^{P, \phi _2^{EOM}}_{0-\lambda ,\mu \lambda }\)  as we found in [1]}.
